Abstract
In 2004, the urban presence of Lutzomyia longipalpis was recorded for the first time in Formosa province. In 2006, the first autochthonous case of human urban visceral leishmaniasis (VL) was recorded in Misiones in the presence of the vector, along with some canine VL cases. After this first case, the vector began to spread primarily in northeast Argentina. Between 2008-2011, three human VL cases were reported in Salta province, but the presence of Lu. longipalpis was not recorded. Captures of Phlebotominae were made in Tartagal, Salta, in 2013, and the presence of Lu. longipalpis was first recorded in northwest Argentina at that time. Systematic sampling is recommended to observe the distribution and dispersion patterns of Lu. longipalpis and consider the risk of VL transmission in the region.
Highlights
The most abundant species in both samplings was Lu. longipalpis
The urban presence of Lutzomyia longipalpis (Lutz & Neiva, 1912) (Salomón & Orellano 2005) was first recorded in Argentina in Formosa province in 2004; it was associated with an outbreak of visceral leishmaniasis (VL) in the neighbouring city of Asunción, Paraguay Republic

Summary
The most abundant species in both samplings was Lu. longipalpis. A total of 277 Phlebotominae were captured. The urban presence of Lutzomyia longipalpis (Lutz & Neiva, 1912) (Salomón & Orellano 2005) was first recorded in Argentina in Formosa province in 2004; it was associated with an outbreak of visceral leishmaniasis (VL) in the neighbouring city of Asunción, Paraguay Republic.
